Leprosy is a good example of a ring-like skin lesion
Answer:
crossing over
Explanation:
Crossing over is where homologs can exchange DNA which leads to genetic variation
Answer:
Ll, Ll, LL
Explanation:
So, there is one thing we must remember to answer this:
1# dominant genes(long fur) are expressed over reccesive genes(short fur)
Knownign that dominant is over reccesive, it is simple. If the genotype was Ll or lL then the dominant long fur would be expressed over reccesive short fur. <u>Long fur - Ll, lL</u>
Next, we know that LL will be long fur since its both long and long, and there is no possibility for short fur. <u>Long fur - LL</u>
Finally. we have ll, and since there isnt a dominant long fur, and only reccesvie short, then this cannot be long fur. Short fur. - ll
Answer:
(a) crossing over: Meiosis I, Recombination
(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II
(c) chromosomes become aligned in pairs at the equator: Meiosis II, Metaphase II
Explanation:
Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.
Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.
Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.
Answer:
The correct answer is - a lower frequency and a longer wavelength.
Explanation:
According to the question and generally, some snakes have special organs that can sense or detect the Infrared region of the electromagnetic spectrum. However, human eys can not see or detect the infrared region.
Infrared waves have a longer wavelength and lower frequency in comparison of visible light, visible light can be seen by human eyes.
Thus, the correct answer is - a lower frequency and a longer wavelength.
